It seems like $acceptHeader can also be of type null or object<Neomerx\JsonApi\Http\Headers\Header>; however, Neomerx\JsonApi\Contracts\Http\HttpFactoryInterface::createHeaderParameters() does only seem to accept object<Neomerx\JsonApi\Contracts\Http\Headers\AcceptHeaderInterface>, maybe add an additional type check?

It seems like $contentTypeHeader defined by null on line 55 can be null; however, Neomerx\JsonApi\Contracts\Http\HttpFactoryInterface::createHeaderParameters() does not accept null, maybe add an additional type check?
